NAME

       JSON::RPC - Perl implementation of JSON-RPC 1.1 protocol

DESCRIPTION

	JSON-RPC is a stateless and light-weight remote procedure call (RPC)
	protocol for inter-networking applications over HTTP. It uses JSON
	as the data format for of all facets of a remote procedure call,
	including all application data carried in parameters.

       quoted from <http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html>.

       This module was in JSON package on CPAN before.	Now its interfaces was completely changed.

       The old modules - JSONRPC::Transport::HTTP and Apache::JSONRPC are deprecated.  Please try to use JSON::RPC::Server and JSON::RPC::Client
       which support both JSON-RPC protocol version 1.1 and 1.0.

EXAMPLES

       CGI version.

	#--------------------------
	# In your application class
	package MyApp;

	use base qw(JSON::RPC::Procedure); # Perl 5.6 or more than

	sub echo : Public {    # new version style. called by clients
	    # first argument is JSON::RPC::Server object.
	    return $_[1];
	}

	sub sum : Public(a:num, b:num) { # sets value into object member a, b.
	    my ($s, $obj) = @_;
	    # return a scalar value or a hashref or an arryaref.
	    return $obj->{a} + $obj->{b};
	}

	sub a_private_method : Private {
	    # ... can't be called by client
	}

	sub sum_old_style {  # old version style. taken as Public
	    my ($s, @arg) = @_;
	   return $arg[0] + $arg[1];
	}

	#--------------------------
	# In your triger script.
	use JSON::RPC::Server::CGI;
	use MyApp;

	# simple
	 JSON::RPC::Server::CGI->dispatch('MyApp')->handle();

	# or
	JSON::RPC::Server::CGI->dispatch([qw/MyApp FooBar/])->handle();

	# or INFO_PATH version
	JSON::RPC::Server::CGI->dispatch({'/Test' => 'MyApp'})->handle();

	#--------------------------
	# Client
	use JSON::RPC::Client;

	my $client = new JSON::RPC::Client;

	my $uri = 'http://www.example.com/jsonrpc/Test';
	my $obj = {
	   method  => 'sum', # or 'MyApp.sum'
	   params  => [10, 20],
	};

	my $res = $client->call( $uri, $obj )

	if($res){
	   if ($res->is_error) {
	       print "Error : ", $res->error_message;
	   }
	   else {
	       print $res->result;
	   }
	}
	else {
	   print $client->status_line;
	}

	# or

	$client->prepare($uri, ['sum', 'echo']);
	print $client->sum(10, 23);

       See to JSON::RPC::Server::CGI, JSON::RPC::Server::Daemon, JSON::RPC::Server::Apache JSON::RPC::Client and JSON::RPC::Procedure.
